Plasma display panel and plasma display device

A plasma display panel comprising:

• a first substrate;
• a second substrate;
• and discharge gas filled between said first and second substrates,
• wherein said first substrate includes:
• a group of first electrodes for performing sustain discharge and a group of second electrodes which can be independently driven, said first and second electrodes being alternately disposed approximately in parallel to each other;
• a group of third electrodes located between said first and second electrodes;
• a dielectric layer covering said groups of the first to third electrodes;
• a group of fourth electrodes provided on said dielectric layer so as to intersect with said first to third electrodes;
• and a protective layer provided so as to cover said dielectric layer and said group of the fourth electrodes, and
• said second substrate includes:
• barrier ribs provided in parallel to said fourth electrode so as to divide at least said
• first to third electrodes in the extending direction thereof;
• and phosphors for emitting light when excited by ultraviolet rays.
